No. Sometimes there is no useful referring URL and sometimes it is
omitted for other reasons.

For example, in Opera (at least for some versions) the user can easily
disable the referrer (or referer) logging.

You can do it also in Mozilla Suit and Firefox. What I wonder is, did
many disable that and why, if they do? :)

Some firewalls can also disable it. Kerio
<http://www.kerio.com/us/kpf_home.html> does this by default.

People disable it because they do not want it know where they came from,
similar to why people disable cookies, privacy reasons.

I worked for a french website that was used by french users, mainly from
their work. The referer was not sent for almost 10% of the whole 400 000
unique visitors each months... This is a big proportion.
